MACHINE FOR CUTTING BORDERS AND TRIMMING WALL-PAPER.

SPECIFIGATIQN forming part of Letters Patent No. 668,945, dated February 26, 1901.

Application filed July 11, 1900.

To (M /T wit/mt it 7714357/ concern/.-

Be it known that l, AARON ALLEN, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in' Vented certain new and useful Improvements in Machines for Cutting Borders and Trimming Vail-Paper, of which the following is a specification.

My invention has relation to a machine for cutting borders and for trimming the edges of wall-paper and the like; and in such connection it relates more particularly to the construction and arrangement of such a machine.

The principal objects of my invention are, first, to provide in a machine of the character described a driving-shaft having a cuttingdisk, a sleeve carrying said disk and splined to said driving-shaft, a bracket having two bearings and supported on said shaft and inclosing said sleeve and disk between said bearings, a second cutting-disk complemental to the first cutting-disk and having a central axis trunnioned in said bracket, and, second, to provide a wall-paper-trimming machinein which two sets of complemental cutters or cutting-disks are used, the machine having a single drivingshaft, to which one cutter of each set is splined, a bracket supported upon the shaft and carrying the other cutter for each set, a rod or bar arranged parallel to the drivingshaft, means for sliding the brackets on the rod or bar and the driving-shaft to ad just the two sets of cutters toward or away from each other, and means for shifting the bar or rod longitudinally in the machine, whereby the two sets of cutters may be moved toward or away from either end of the machine to compensate for variations in the selvages or edges of the untrim med paper.

My invention, stated in general terms, consistsof a border-cutting and wall-paper-trimming machine constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of myinvention will be more fully understood from the following description taken in connection with the accompanying drawings, forming part hereof, in which- Figure 1 is a top or plan View of a machine Serial No 23,173- (No model.)

embodying main features of my invention. Fig. 2 is a front elevational view thereof with certain portions sectioned to more clearly illustrate the same. Fig. 3 is an enlarged detail view of one set of the cutters, the view being partly in front elevation and partly in longitudinal section. Fig. 4 is an end elevational view of Fig. 3; and Fig. 5 is a top or plan view of the cutting-disks, illustrating the oblique arrangement of the axes of the said disks.

Referring to the drawings, a a represent the end or side frames of the machine. These frames form the bearings for the main driving-shaft b and the hand or power shaft d, having preferably its hearings in one side frame a only. The shaft- 7) and power-shaft d are geared together by suitable gears 19' and d, and the shaft 01 is preferably operated by a handle (1 The driving-shaft b is longitudinally grooved, as at 5 to form a spline for two sleeves e 6. each of which carries a cutter-disk ff. The sleeves e e fit the shaft 1) and are locked thereto, so as to be rotated therewith, by means of suitable screws or pins e, entering the groove b The sleeves c e are by reason of the screws 6' and groove b longitudinally movable on the shaft 17, so as to be capable of adjustment toward or away from each other. On the shaft 1) is loosely fitted a bracket g, substantially G-shaped. The upper portion of this bracket has two bearings g and in which the shaft 1) rotates, and between these bearings g and g a sleeve 6 and its diskf are located. The lower convolution of each bracket g is provided withtwo trnnnions h and it, between which the short shaft 77. is loosely supported. To each shaft 71 is secured a complemental cutter-disk m, which is so located with respect to the complemental diskf that the cutting edges of both disks are contiguous. On the short shaft h is also located an adjustable tension device at, designed in the well-known manner to press the disk m toward the other diskf. The trunnioned shaft 71 is not arranged parallel to the shaft 1), but obliquely thereto, as clearly illustrated in Fig. 5. By reason of this oblique arrangement of the axes of the two complemental disksfand m the peripheries or cutting edges of said disks approach each other sufiiciently to cut the material at a single ICO point instead of, as heretofore, the peripheries lapping for an appreciable length of arc. By this means the severance of the paper is accomplished more clearly and the wear upon the cutting edges of the disks distributed more uniformly.

The two sets of complemental disks f and m, together with their brackets g, are adapted to be slid on the shaft b toward or away from each other to assume a width corresponding to the width of paper to be cut, and when so slid and adjusted they are fastened in this position in the following preferred manner: Above the shaft 1) and in the frames at ais arranged a bar or rod p, which traverses each bracket g at preferably the upper end of the said brackets. Set-screws p are adapted to secure the brackets g to the rod or bar p, so as to fixthe brackets and the disks carried thereby in the required relationship. In the cutting of wall-paper and the like it has been found that the roll of uncut paper is provided with selvages of more or less irregular width, and heretofore the paper was carried by a shaft which could be shifted longitudinally in the machine, so as to bring the paperin proper position with respect to the on tting-disks, so that said disks would travel along the marks or lines of severance. In the present machine the roll of uncut paper is not thus shifted, but provision is made for shifting the two sets of cutting-disks, as follows: The rod or bar 19 may be longitudinally shifted -or adjusted, as occasion demands, and will carry with it in its movement the two brackets g and the two sets of disks f and on. To accomplish this, one end of the rod or harp is threaded, as at 10 and extends through and beyond the side framed to receive a nut 19 The bar or rod 19 also has a collar p near its threaded end, and between this collar 19 and the inside of the frame a is located a spring 19 which spring is preferably coiled around the rod 19. It will be readily understood that by advancing the nut 10 the rod or bar 19 will be shifted't'rom left to right against the tension of the spring 10 while by loosening the nut 19 the spring 19 will shift the rod p from right to left. The ad vantage of this arrangement over the old way of shifting the paper will be manifest when it is understood that when the paper is shifted the strain thus occasioned causes the paper to wrinkle and to twist, while when the disks are shifted, as in my present arrangement, the paper is not disturbed, but continues to be fed to the disks in a smooth and unwrinkled condition. Each bracket 9 is provided with a pin or rod r, adjustable in the bracket toward or away from the lower portion of the cutter-diskf and acting as a selvage-clearing device.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the character described, a driving-shaft, a cutting-disk, a sleeve carrying said disk and splined to said drivingshaft, a bracket having two bearings and supported on said shaft and inclosing said sleeve and disk between said bearings, a second cutting-disk complemental to the first cuttingdisk and having a central axis trunnioned in said bracket, substantially as and for the purposes described.

2. In a machine of the character described and provided with two sets of complemental cutting-disks, a single driving-shaft to which one disk of each set. is splined, two brackets supported upon the shaft and each carrying the complemental disk of each set, a rod or bar arranged parallel to the driving-shaft and traversing each bracket, means for securing the brackets to said rod or bar, and means for shifting said rod or bar longitudinally in the machine to thereby shift both sets of cutting-disks simultaneously and longitudinally in the machine, substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.

AARON ALLEN.
